TRUNK-LOCK.

SPECIFICATION forming part of Letters Patent No. 499,971, dated June 20, 1893.

Application filed December 1 1892.

To all whom it 11i/ay concern:

Be it known that I, WILLIAM J. DAVIS, of Charlotte, in the county of Mecklenburg and State of North Carolina,have invented a new and useful Improvement in Trunk and Valise Fastenings, ot' which the following is a full, clear, and exact description.

Myinvention relates to improvements in a class of trunk, boX,or valise fasteniugs, in

which the main lock co-acts with other attachments, and effects a locking adjustment of the latter when the main lock is manipulated to lock it 5 and my invention consists in the peculiar construction `and combination of parts, as is hereinafter described and claimed. Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure lis a front perspective view of a trunk and the improved locking device thereon shown partly in dotted lines. Fig. 2 is an enlarged, broken and partly sectional view on the line 2-2 in Fig. 3, of the inner side of the front wall portion of a trunk lid, a trunk body front wall broken and in part, and the improvement on said parts in full and dotted lines. Fig. 3 is a transverse section of parts of the trunk lid and body and the improvement in a locked condition, on the line 3-3 in Fig. 2. Fig. 4 is a transverse sectional View of parts on the same line asFig. 3, the locking device being in unlocked condition. Fig. 5 is an enlarged and detached inner side view of the hasp plate and its securing piece to which the hasp is pivoted, taken opposite the arrow 5, in Fig. 3; and Fig. 6 is a partial transverse section of the trunk body front wall,

. the closed lid front wall in part, and an improved supplementary locking device, on the line 6-6 in Fig. 2.

The lock proper for the trunk A, of which 0J represents the case, may be of any preferred form in 'a class having a horizontal slide bolt, indicated at b, in Figs. 3 and 4:, the other parts being omitted.

The lock case a, is secured with the interior mechanism, when the latter is in place therein, upon the front wall of the trunk body at the longitudinal center, and near the top edge of the body; said case being located in a Serial No. 453,'7Z. (No model.)

proper shaped cavity formed in the side wall of the trunk.

The hasp piece o, is of the usual form, com` lprising an oblong plate of suitable dimensions, and by preference flanged along the edge on the inner surface, to stiften the plate. A bracket plate d, is provided, for an attachment of the hasp piece c, upon the front side of the trunk lid A', two trunnions c', which project Oppositely from the sides of the hasp near its upper edge and which are located in recesses formed in projections c2, on the bracket plate, serving to loosely connect the bracket plate and hasp piece. The bracket plate d, is cut away of a suitable width and height from its lower edge, to allow the hasppiece to vibrate between the projections c2;

the thin keeper plate d', which covers the rel hasp piece to adapt it to retain the trunnions in place and permit a free vibration of the hasp piece outwardly and upwardly.

A recess e, is cut in the front wall of the trunk lid Aabove the case a, for the reception of other features that are part of the improvement and which will presently be described. A rectangular base plate g, is furnished of sufficient area to cover the recess e, and be secured by its overlapping edges zto the side wall of the lid, the bracket plate d, being imposed upon the outer side of the base plate and thereto secured by any preferred means. Two similar iat L-shaped levers h, are pivoted at their angular corners h upon the inner surface of the base plate g, so that their main limbs will-hang pendent and their lateral limbs overlap each other as indicated in Fig. 2. The lapped horizontal limbs of the levers h, are each slotted from their free ends toward the pivots of the levers a proper length,

forthe reception of an arm 7l, that projects IOO centrally, said loop having its body in a vertical plane, which will permit it to enter a slot m', formed in the outer wall of` the lock case a, and cross the path of the slide bolt b, in

said case, so that the horizontal projection of the bolt Will secure the hasp in the case and a reverse movement o-f said: bolt release the hasp as is usual in this class of locks.

Fromthe lower end of each of the levers h,"

a slide bar n, is projected, which barsare era.-` tended toward the end Walls of the trunk lid,

. and preferably are located in longitudinal grooves produced in the lower edge ot' the front wall of the lid,as representedin Fig.-2.

It will be seen, that the slide bars n, are each loosely connected to an end of the pendent limb of a lever h, that is farthest from the other end of the barso that'the divergence of these pendent limbs of the levers h,

will vdraw the outer ends of the bars away.`

from the end walls of the trunk lid, and an opposite movement of the pendentleerlimbs that' will cause their ends to approach each other, will project the free ends ot" the bars toward these end Walls of the lid,iu an obvi.-

ous manner.

The slide bars n are of such a proportionate length, as will adapt their outer ends to slide through two supplementary lockingxlevices, which are each formed of a socket, piece o, and a tongue piece o', which are secured in matingpairs at a proper distance fromthe main lockingdevice before described.

Asshown in Figs. 2 and 6, the tongue and f socket pieces are respectively secured` upon,

the inner sides of the front Wall of thetlunk and; the front wall of the lid, so that, the.` slightly tapered tongue on thepieces0.',[willA freely enter the socket holesin' the pieces o, when the lid' is closed,there beingsui'tablerecesses cut-.in the lid and trunk walls to allow the pieces o o', to be embeddedandv secured" therein with their inner faces fiush with the inner faces of the parts to which they aresefA cured.

The mating tongue and socket pieces o, 0

are in pairs transversely perforated, at such points as will cause the holes on all the pieces to lie in about the same horizontal plane, when the lid is closed, thereby permitting the end portions of the slide bars l1L, tha'tjaregnearest toA these parts, to slide through the aligned' u holes-when the hasppiece c, isvibrated towardi the lock case a, which will secure the mating socket andtongue pieces o, o', together in pairs. Whenthe locka and hasp piece c.

are fastened together by a proper'key, that is adapted to slide the bolt b, and Work other parts of the'main lock so as to retain this bolt in locked adjustment, said lock, together with the slide bars and interlocked tongue and :socket piecesio, o, willti'rmly lock the lid `A, on the trunk body A, at three diierent points, thus dispensing with other appliances lthatare usually provided to latch the trunk lid fast to the body of the trunk, and release 'the main lock from strains incurred through rough `handling of the trunk.` l

It will be evident, that by a proper proporvtion of parts, the improvement may be applied to secure the hinged and folding portions of a valise together, locking theulat three points, and requiring the mainlock, toA be unlocked and hasp pieces vibratedither from to release the supplementary locks that are near the endsof the receptacle.

Having thus described my invention, what .I claim as new, and desire yto secure by Letters Patent, isp y 1. The, combination, with a receptacle, a-` {hinged` lid therefor,a hasp vibratable on a.
